A data driver including a receiver, a skew adjusting circuit and a processing device is provided. The receiver samples image data on a data bus according to a processed pixel clock signal. The image data includes pixel data during active periods and a test pattern repeatedly inserted in the image data during blanking periods. The skew adjusting circuit receives a pixel clock signal and adjusts a clock phase of the pixel clock signal by delaying the pixel clock signal with a controllable skew according to a feedback control signal so as to generate the processed pixel clock signal. The processing device stores a predetermined test pattern synchronized with the inserted test pattern, determines an optimum skew by comparing the sampled test patterns with the predetermined test pattern, and generates the feedback control signal including information indicating the optimum skew.

A method for detecting whether or not a display mode has to be switched and for detecting a frame of a liquid crystal display panel. The frame has M vertical blocks each including K display lines each having N horizontal blocks each being composed of multiple display units. First, a horizontal block flag value of each horizontal block is obtained according to energy levels of all of the display units of the horizontal block. Then, a display line flag value of each display line is obtained according to horizontal block flag values of all of the horizontal blocks of the display line. Next, M vertical block flag values are obtained according to the display line flag values of all of the display lines in each vertical block. Then, it is determined whether or not the display mode has to be switched according to the M vertical block flag values.
